Real Audio (.RAM) files were designed specifically for streaming audio on the internet. Since the quality of streaming audio is directly related to the bandwidth, higher quality Real Audio files can be created for high-speed internet (DSL, cable modem) users and lower-quality Real Audio files can be created for low-speed (dial-up). Real Audio files don't have the sound quality of MP3s, but their upside is the streaming and their smaller size. A five-minute Real Audio file created for 56K modem users takes up about 1.25 MB (1/4 of an MP3). Recordings of speeches or sermons don't require the same kind of quality as music, making Real Audio ideal for them.
